Donk's heart throbbed in his chest as he reluctantly pushed open the common room door and stepped inside. His frat brothers' laughter filled the room, their merriment echoing off the wood-paneled walls. Stripped down to their bare essentials, they cavorted and brayed, their antics amplified by the pieces of the Donkey-At-Home Costume they wore.
Chad, the frat brother Donk had quietly harbored a crush on for the last two years, was the sight that drew his attention. Naked except for the four donkey hooves he wore, Chad's muscular physique was on full display. His muscular back and firm buttocks, usually hidden under layers of fabric, were now bare and unhidden. Donk swallowed hard, his face growing hot. Chad caught his eye and gave him a mischievous grin, knowingly, like he had discovered Donk's secret and was using it to his advantage.
"Come on, Donk," Chad brayed, adopting a playfully persuasive tone, "Get your ass over here." He then moved onto all fours, offering his back to Donk. "Why don't you hop on and ride me? I promise you won't forget it!"
Chad's invitation felt like a siren's call to Donk. His heart pounded in his chest as he gingerly approached Chad, a feeling of fear and thrill simultaneously running through his veins. His hands trembling slightly, Donk mounted Chad's back, his fingers curling into the sturdy muscles of Chad's shoulders.
As Chad trotted around the room, Donk couldn't help but let his mind wander. He imagined running his fingers through Chad's dark hair, exploring his muscular torso, whispering sweet nothings into his ears as they both lost themselves in the pleasure of their closeness. These fantasies had been his secret for so long, and now they seemed to be playing out before him, in an admittedly absurd and somewhat humiliating way.
Donk was brought out of his reverie by a holler from Jack. "Hey Donk! Why don't you put on a piece of the costume too?"
The suggestion was met with an eruption of agreement from the frat brothers, who started chanting "Donk! Donk! Donk!". Looking around the room, he felt his nerves take a grip on him. Still, not wanting to back down, Donk decided to play along.
"Alright, alright," Donk said, dismounting from Chad and reaching for the donkey tail that lay abandoned on the floor. He tried to attach it to his jeans, but it didn't stick, instead falling limp onto the ground. He sighed, then, remembering the tag's instructions, hesitantly started to undress, stopping only at his boxers.
Andy and Jack looked at each other and shared a mischievous grin before they lunged at Donk. He tried to dodge, but they were too quick, pushing him onto the floor and holding him down. His face turned a deep red as he tried to cover his obvious arousal, embarrassed and yet slightly excited at the same time.
Chad, seeing his predicament, trotted over, his hooves clacking against the wooden floor. "Let me help you out, buddy," he said, reaching down with a hoof to try and pull down Donk's boxers. He struggled a bit, unable to get a grip. In a sudden moment of inspiration, he bent down and hooked his mouth onto the waistband, pulling down Donk's boxers. Donk gasped, his cheeks burning. The room erupted in laughter once more.
Donk quickly attached the tail, feeling a strange sensation as it seemed to fuse with his skin. He stood up, adjusting the tail as he experimented with wagging it. The costume piece was surprisingly lifelike, moving with a mind of its own. As he imitated various animals, there was an unusual tickling sensation at the base of the tail, causing him to wiggle it even more.
While he was distracted, he didn't notice that his frat brothers were transforming further. They were getting hairier, and Chad, who still had Donk's boxers in his mouth, was mindlessly chewing them. When Donk noticed, he couldn't help but laugh and playfully tickle Chad, who dropped the boxers but decided to find a new source of Donk's scent. He nuzzled into Donk's armpit, inhaling deeply.
"Chad, what the-" Donk began, but his surprise quickly melted into pleasure as Chad's lips found his. The kiss was passionate and heated, and Donk could barely register what was happening.
But before things could go any further, a loud knock echoed through the room, causing them to jump apart. The laughter and merriment came to a halt, the room falling into silence. As the knock came again, louder this time, they shared confused glances.
